• We model the evolution of indirect reciprocity, using reputation spreading process.
• We examine the effects of false information intentionally started by some players.
• More and more gossip sessions are favored when no players start false info...

This study aimed to assess the suitability of luteal blood flow analyses measured by color Doppler ultrasonography (CDUS) to predict pregnancy at pre- and post-embryo transfer (ET) in dairy cows and to compare with the established criterion like l...

維管束系の生理学的理解は年々深まっているが、篩部構造にはいまだわかっていない点が多い。また生態学的理解、つまりなぜ現存する生物集団内で、特定の維管束系形態が維持されているかについては、アプローチ自体がほとんどなされていない。本稿では、適切な量の栄養を適切な時期に適切な部位に供給することのできた個体が自然選択または人為淘汰によって子孫数を増やしてきたという観点に立ち、篩部ショ糖転流について、生理学モデルを用いた生態学的理解を試みた。具体的題材としてイネを用いた研究を紹介し、ショ糖篩管輸送モデ...

• This study quantified effects of florigen distribution on inflorescence architecture.
• We developed the phloem transportation model for florigen.
• The model predicted diverse inflorescence architectures observed in Arabidopsis.
• The model hig...

Rice (Oryza sativa) is one of the most important food crops in the world. Numerous quantitative trait loci or genes controlling panicle architecture have been identified to increase grain yield. Yet grain yield, defined as the product of th...

According to the viewpoint of the optimal strategy theory, a tree is expected to shed its leaves when they no longer contribute to maximisation of net carbon gain. Several theoretical models have been proposed in which a tree was assumed to strate...

Cultural transmission between individuals can take various forms. One-to-many transmission refers to the case when each individual in a population socially acquires cultural traits from one particular individual who occupies a special social statu...

・ A conflict between autosomal and X-linked altruism toward grandchildren is modeled.
・ With no conflicts, the latter altruism evolves under quite high cost/benefit ratio.
・ The conflict especially makes evolution of the latter kind of altruism di...

Background: Homogamy for body height has been repeatedly documented in Western societies. Nevertheless, the underlying mechanism is unclear and the reasons for its apparent absence in non-Western societies remain unexplained.

Aim: This study inve...

We consider a rumor transmission model with various contact interactions and explore what effect such interactions have on the spread of a rumor, in particular whether they can explain the rumor recursion. Through mathematical analysis and compute...

Male parental care and female multiple mating are seen in many species in spite of the cost they entail. Moreover, they even coexist in some species though polyandry, by reducing paternity confidence of caregiving males, seems to hinder the evolut...

A repeated game is a formal model for analyzing cooperation in long-term relationships. The case where each player observes her opponent's action with some observation errors (imperfect private monitoring) is difficult to analyze, and existing wor...
